problem with injector/ spark plug.??

This is a strange problem. no one iv spoken with has ever heard of something like this. i was driving (87 gn) and all of a sudden its running like hell, popping slow etc. i got it home and popped the hood. i notices a spark plug wire unattached. ( strange, but ok) so i go to reattach it and noticed its hollow. the metal inside the plug is gone, and the ceramic is blown apart. i diddnt have a gapper and dint have the correct gap #s, so i replaced the spark plug with a new one leaving it gapped as it came. a few days ago i notice the fuel injector on the same cylinder was leaking fuel. im not sure which happened first, or even if one can cause the other. what the hell!! anyone have any suggestions?

you did not lose a compressor fin on your turbo did you? or have anything go through your engine?

i dont think so, i had an air filter on, and its a pretty new turbo. 3k miles

where you under boost when you noticed it at all?

what where your o2 milivolts and what plugs do you run? Also, what PSI

yes i was under boost. o2 im not sure, i leave it to the computer, cant find a machanic that knows gns enough to properly tune it. if i had to guess, id say it running a bit rich. the past few months iv kept the boost low, id say 15psi tops

How many miles are on your car and how old are the valve springs.

If you where under boost it is possible you floated your valves and blew the injector out of the bung. The spark plug thing is kinda weird though

yea it is wierd. i have about 110k on the car. about 15k on the trans, 10k on the motor, about 5k on the turbo.

now that you mention it, there is a strange rattle coming from the cat converter. could it rally be that piece of the spark plug? i couldnt see how it would fit through the turbine blades.

???? beats the hell out of me, check your heat shields first.
